IDCompositionMatrixTransform interface

When to implement

Client applications do not implement IDCompositionMatrixTransform; custom implementations are not supported.

When to use

All 2D transforms in DirectComposition can be represented by a 3-by-2 matrix. Use the IDCompositionMatrixTransform interface when you need a type of transformation matrix that is not already implemented by one of the other DirectComposition transform interfaces. Generally, it is slightly more efficient to use one of the other interfaces. For example, always use the IDCompositionTranslateTransform interface to define a translation matrix instead of the IDCompositionMatrixTransform interface.

Members

The IDCompositionMatrixTransform interface inherits from IDCompositionTransform. IDCompositionMatrixTransform also has these types of members:
